' SLICING MACHINE.

Application filed April 15, 1922. Serial No. 552,983.

To all whom it may concern:

Be it known that I, WILLIAM J. CAMP- BELL, a citizen of the United States, residing at lndianapolisf in the county of Marion and State of Indiana, have invented a certain new and useful Improvement in Slicing Machines, of which the following is a specification.

My invention relates to a slicing machine,

and particularly to a, machine which is adapted for both manual and power 0 ration. It has for object to provide a exible, simple and efiicient power plant for drivin a slicing machine which permits manna and electric power to be used at will. Another object is to provide driving means in which all rattle and play shall be efliciently and completel eliminated. Another ob ect is to provi e a machine which may be mechanically 'driven at varying rates of speed. Other-objects will appear from time to time in the course of the specification.

I illustrate my invention more orless diagrammatically in the accompanying drawings, wherein-- Fig. 1 is a side elevation of the frame showing a slicing machine mounted thereon;

Fig. 2 is a new of the driving mechanism inthe same direction as Fig. 1, with the supporting frame in section;

Fig. 3 is a section on the line 3-3 of Fig. 2;

ig. 4 is an inverted plan view of the supporting base frame;

Fig. 5 is a detailed sectlon along the line 55 of Fig. 3; and h Fig. 6 is a detail showing a modified form of motor suspension.

Like parts are indicated by like characters throughout the drawings.

A isa tapered wall pedestal having the bottom support Aand the removable side panels A. Mounted in the pedestal are opposed bearings A'A and A A9, each bearing being provided with a removable ca A Mounted on these hearings are shafts A A.

Keyed to the shaft A is thepulley B, about which travels the belt B, which is driven by the pulley B on the motor B.

- The motor is mounted on the support C, which is provided with the cross-member C pivoted on the base tothe supports C C. The opposite end of the support 0 1s perforated with an to receive the bolts C G which are axially movable in the lugs C inwardly projecting from the pedestal. Nuts C C en ge either side of the lug C and rotation o the screw C serves to lift or depress the support C and thus vary the position of the motor in relation to the pulley B. A cross element C removably bolted to the pedestal, as at C C, serves to limit the movement of the base C in a downwarddirection.

Keyed to the shaft A are the pulleys D D, one being of considerably larger diameter than the other. Belts D D furnish a driving connection between these pulleys with the pulleys D D rotatably mounted on the shaft-A These ulleys are provided suitable .elutc elements, for example t e toothed surfaces D D", which are adapted to be engaged by similar opposed surfaces on the clutch element D,

which is feathered to the shaft A and conb the action of the automatic tension levers" E each of which is provided with a belt engaging roller E the lower end of each lever being operated on by a spiral sprin E? attached as at E to the side of the plehestal opposite to the tension lever. upper end of the levers are pivotally mounted, for example on the rod E.

Keyed to the shaft A is a sprocket element F adapted to drive the sprocket chain F which in turn drives the sprocket member F on the slicing machine shaft F. The slicing machine proper is not concerned in the present invention and will not be further described.

The top of the pedestal is provided with flanges G, which are each perforated to receive a screw-threaded bolt G which has a stop G and an upper cylindrical portion G adapted to engage perforations in the bottom of the slicing machine. These bolts obviously are separatel adjustable and may .be raised or lowered y rotation of the nut ings 'be regarded as largely diagrammatic.

. It will be understood that while I have shown and described an operative device, still many changes might be made in the number, size, shape and relation of parts without departing from the spirit of my in'- vention. I wish, therefore, that my draw- The use and'operation of my invention are as follows:

I provide what. amounts to a power plant for slicing machines, which is inclosed withmotor mounted within the make a terrific din. I therefore provide for.

tension on the belt by mountin the motor on ahinged base and by positive y adjusting the position of the base and motor in relation to the pulley by rotating thescrew C, as shown in Fig. 3. The tension may thus be initially set and may, of course, be adjusted from time to time as the operation of the machine warrants. I may also dispense with the positive connection and merely suspend the motor within the belt B further adding to the tension by the spiral spring X, but the first mentioned form seems at present preferable.

The transverse member C serves as a stop to limit the motion ofthe support C, and even if the belt comes off and the screw C is rotated to lower the base as far as it can be lowered, the motor cannot drop through the, bottom of the machine. This is particularly important in connection with the form shown in Fig. 6. This is also particularly useful .as permittinga ready removal of the motor in one cleaning or repair is necessary, or in case the user wishes to substitute another motor or type of motor.

.The member C is simply removed and the ede'stal may then be tilted over on its side, eaving the support C with the motor thereon lying in freely available position.

T e pulley B positively drives the shaft A, androtating with the shaft are two pulleys of varying size, the smaller one, of course, givin a slower movement to the belt driven by it t an the larger one. These two pulleys and the belts which they drive in turn drive two pulleys of equal size rotatably mounted on the upper shaft A, each of the ulle s being constantly driven when the sha A is in motion. I provide a clutch elevm'ent feathered to the shaft between .the two pulleys, which may be alternatetliy thrown mto o erative'engagement with the ot er dependin on whether a high or low speed drive is desired. When it is. in neutral, both pulleys simply spin on the One 01 an of course, drives the shaft A without giving any rotation to the two pulleys oosely mounted thereon. The simple external control lever provides for varying the speed or throwing the clutch out.

Fig. 1 shows the eneral disposition of the device, but since t e details of the slicing machine proper do not form part of the present invention it is not'described, beyond stating that it consists of a rotary knife, 8. support for grippin the material to be cut,

means for feeding t is support forward to- I ward the knife, and means for reciprocating it back and forth across the face of the knife.

The bottom of the'slicing machine is provided with holes which fit the studs Gr at the to of the bolt G'. An adjustment of these bo ts-permits a leveling or centering of the slicing machine on the base, to correct for irregularities of'the base, or rather of the floor on which it rests.

An even more important function of these studs is the adjustment of the tension of the flexible chain F' which provides the driving connection'between' the power plant in the base and the shaft F of the machine. If the chain is loose and tends to rattle, the studs ma be lifted to raise the slicing machine bo ily on the base and thus to correct the tension of the chain by increasing the distance between the sprockets.
